introduction： Schematic diagram of working principle The core component of high speed dispersing emulsifier is a pair of rotor and stator meshing with each other。The same number of slender cuts are made around the stator。When the rotor is spinning at high speed，It creates a lot of centrifugal force，Make the material to be treated through the slender incision in the rotor（slit）Intermediate eruption。And under the joint action of the stator，The material being treated is subjected to two forces：The positive force forcing it through the slit and the resistance preventing it from going through。This process is repeated at high speed，High frequency pressure waves must be generated。meanwhile，When the material being treated is ejected from the slit，Its also subjected to slit shear
